Question

find the value of m in following
​

Answer 1

Answer:

10° is. your answer

Step-by-step explanation:

please follow

Answer 2

Please refer attached image for diagram

∠BCN and ∠BCP are linear angles hence

∠BCN + ∠BCP = 180

∠BCP = 180-56 = 124

Similarly,

∠EDC = 180-50 = 130

Sum of interior angles of pentagon is 540

$∠A + ∠B + ∠C + ∠D + ∠E =540° \\ 34 + m + (m - 10) + 124 + 130 = 540 \\ 2m + 158 + 120 = 540 \\ 2m = 540 - 278 = 262 \\ m = \frac{262}{2} = 131$
